The invention relates to a tramcar vibration-absorbing and noise-damping structure which is applied in a concrete grooved steel rail of a tramcar. The tramcar vibration-absorbing and noise-damping structure comprises a first rubber element, a second rubber element and a rail bottom cover, the first rubber element and the second rubber element are positioned on two sides of the grooved steel rail respectively, the rail bottom cover is wrapped at the bottom of the grooved steel rail, barbs extending inwards from the bottom of the grooved steel rail are arranged on two sides of the rail bottom cover to fix the rail bottom cover at the bottom of the grooved steel rail, and the first rubber element and the second rubber element are connected to the barbs on the two sides respectively. The tramcar vibration-absorbing and noise-damping structure is suitable for rail-bound grooved steel rails and further applicable to different section forms, vibration-absorbing and noise-damping effect on a tramcar system can be effectively realized, and stray current between the grooved steel rail and concrete can be effectively isolated.
Description
technical field [0001] The invention relates to a tramway vibration-absorbing and noise-absorbing structure, in particular to a vibration-absorbing and noise-absorbing structure that is applied to the technical field of tramway rail transit vibration reduction and noise reduction and is bonded to the surface of a tramway grooved rail to reduce driving noise. structure. Background technique [0002] Relying on urban rail transit to solve public transportation in densely populated areas has the advantages of large capacity, safety and speed, energy saving and environmental protection. Modern trams are continuously developed on the basis of old-fashioned trams. Foreign trams have always been used as classic urban rail transit tools. Chinese trams have been demolished to the present planning and reconstruction or new construction. This kind of construction period is short, A green and low-carbon transportation system with low cost and quick results can effectively solve urban r...
